Hi Simon, new brushes it will be. I was more concerned about the condition of the commutator but close look last night shows it to be in good condition, a quick clean with the comm cleaner stick is all that's needed. Bearings good as well.
What's of concern now is that the control box relays do not respond with the demist test. I have 3 working relays and good continuity from the pair of connectors to the control box relays/motor. There is 12 volts down to the control box, black and brown wires. A relay clicks in the under bonnet fuse box, not sure which one, will check. I've checked the fuses. Are any of the relays there part of the demist circuit?
John
